Casper wants to keep you cool all summer long so they’re taking $75 off any mattress when you buy an additional productwith promo code FOURTH. You’ll even have a100-night trial to sleep on the Casper at home for months without committing.

Both Casper’s shopping experience and their mattress have been thoughtfully engineered to ensure every step of the experience is ideal. Here’s how:

While memory foam is supportive and comfortable it tends to retain heat, so with the added top layer of breathable foam, the Casper mattress keeps you cooler whileaddingnatural bounce to the support below.

The Casper ships for free and rolled into a small box that can fit through any doorway.

If you decide it’s not for you during the trial, they’ll send someone to pick up the bed for donation and refund your purchase.
